source:interestingengineeringFor the first time, Japanese scientists have found evidence that rare earth elements are indeed made when two neutron stars merge. The Astrophysical Journal just published the specifics of the scientists' discoveries.Many of the heavy atoms that make up our universe are created in the explosion that occurs when two neutron stars spiral inward and merge.The first verified incidence of this process, GW 170817, occurred in 2017. Despite this, except for strontium, recognized in optical spectra, scientists have struggled to pinpoint the precise elements produced du...

Inexpensive Catalysts and Syzygy Plasmonics Photoreactors Open the Door for Broader Hydrogen Adoption source:prnewswireHOUSTON, Dec. 6, 2022 /PRNewswire/ -- Scientists from Syzygy Plasmonics have engineered a new kind of reactor designed to work with earth-abundant, light-activated catalysts created by a joint team from Rice University's Laboratory for Nanophotonics, Syzygy Plasmonics, and Princeton University's Andlinger Center for Energy and the Environment. The reactors use light instead of heat from combustion to power chemical reactions and can produce clean-burning hydrogen ...

A Scalable Quantum Memory with a Lifetime over 2 Seconds and Integrated Error Detection source:hpcwireQuantum memory devices can store data as quantum states instead of binary states, as classical computer memories do. While some existing quantum memory technologies have achieved highly promising results, several challenges will need to be overcome before they can be implemented on a large scale.Researchers at the AWS Center for Quantum Networking and Harvard University have recently developed a promising quantum memory capable of error detection and with a lifetime or coherence time (i.e...

source:pv-magazineLSCs are commonly used as photonic devices in the production of fine chemicals in photomicroreactors, in dynamic “smart” windows to control light entering spaces, and for distribution of color-tuned light to enhance plant growth in greenhouses. They can also be used to improve the efficiency of solar panels. The LSCs consist of luminescent materials that are also known as luminophores, which are groups of molecules that emit light when illuminated.The materials can be coated on the surface of a polymer or glass plate, or used as a dopant of the polymer or glass plate acting a...
